* MdeModulePkg/Core/Dxe: Acquire a lock when iterating gHandleListHua Ma2021-10-144-41/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | | REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3680 This patch fixes the following issue: The global variable gHandleList is a linked list. This list is locked when a entry is added or removed from the list, but there is no lock when iterating this list in function CoreValidateHandle(). It can lead to "Handle.c (76): CR has Bad Signature" assertion if the iterated entry in the list is just removed by other task during iterating. Currently some caller functions of CoreValidateHandle() have CoreAcquireProtocolLock(), but some caller functions of CoreValidateHandle() do not CoreAcquireProtocolLock(). Add CoreAcquireProtocolLock() always when CoreValidateHandle() is called, Also, A lock check is added in the CoreValidateHandle().

* MdeModulePkg/Core/Dxe: Add lock protection in CoreLocateHandleBuffer()Hua Ma2021-10-081-13/+51
| | | | | | | | | | | | | | | | | | | | | | | | REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3666 Currently, CoreLocateHandleBuffer() follows three steps: 1) get the size of protocol database firstly 2) allocate the buffer based on the size 3) get the protocol database into the buffer There is no lock protection for the whole three steps. If a new protocol added in step 2) by other task, e.g. (event timer handle USB device hotplug). The size of protocol database may be increased and cannot fit into the previous buffer in step 3). The protocol database cannot be returned successfully, EFI_BUFFER_TOO_SMALL error will be returned. This patch adds the lock to protect the whole three steps. It can make sure the correct protocol database be returned.

* MdeModulePkg/Core/Dxe: limit FwVol encapsulation section recursionLaszlo Ersek2020-11-212-2/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The DXE Core sets up a protocol notify function in its entry point, for instances of the Firmware Volume Block2 Protocol: DxeMain() [DxeMain/DxeMain.c] FwVolDriverInit() [FwVol/FwVol.c] Assume that a 3rd party UEFI driver or application installs an FVB instance, with crafted contents. The notification function runs: NotifyFwVolBlock() [FwVol/FwVol.c] installing an instance of the Firmware Volume 2 Protocol on the handle. (Alternatively, assume that a 3rd party application calls gDS->ProcessFirmwareVolume(), which may also produce a Firmware Volume 2 Protocol instance.) The EFI_FIRMWARE_VOLUME2_PROTOCOL.ReadSection() member performs "a depth-first, left-to-right search algorithm through all sections found in the specified file" (quoting the PI spec), as follows: FvReadFileSection() [FwVol/FwVolRead.c] GetSection() [SectionExtraction/CoreSectionExtraction.c] FindChildNode() [SectionExtraction/CoreSectionExtraction.c] FindChildNode() // recursive call FindChildNode() is called recursively for encapsulation sections. Currently this recursion is not limited. Introduce a new PCD (fixed-at-build, or patchable-in-module), and make FindChildNode() track the section nesting depth against that PCD.

* MdeModulePkg/Core/Dxe: assert SectionInstance invariant in FindChildNode()Laszlo Ersek2020-11-211-6/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | FindChildNode() has two callers: GetSection(), and FindChildNode() itself. - At the GetSection() call site, a positive (i.e., nonzero) SectionInstance is passed. This is because GetSection() takes a zero-based (UINTN) SectionInstance, and then passes Instance=(SectionInstance+1) to FindChildNode(). - For reaching the recursive FindChildNode() call site, a section type mismatch, or a section instance mismatch, is necessary. This means, respectively, that SectionInstance will either not have been decreased, or not to zero anyway, at the recursive FindChildNode() call site. Add two ASSERT()s to FindChildNode(), for expressing the (SectionSize>0) invariant. In turn, the invariant provides the explanation why, after the recursive call, a zero SectionInstance implies success. Capture it in a comment.

* MdeModulePkg/Core/Dxe: log memory base and length, after lib ctors againLaszlo Ersek2020-11-061-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CoreInitializeMemoryServices() logs "BaseAddress" and "Length" with DEBUG() before DxeMain() calls ProcessLibraryConstructorList() explicitly. (Library construction is not an automatic part of the DXE Core entry point.) So those DEBUG()s in CoreInitializeMemoryServices() are issued against an un-constructed DebugLib, and also against a -- possibly underlying -- un-constructed SerialPortLib. Some DebugLib instances can deal with this (see for example commit 91a5b1365075, "OvmfPkg/PlatformDebugLibIoPort: fix port detection for use in the DXE Core", 2018-08-06), while some others can't (see for example the DebugLib instance "MdePkg/Library/BaseDebugLibSerialPort/BaseDebugLibSerialPort.inf" coupled with the SerialPortLib instance "ArmVirtPkg/Library/FdtPL011SerialPortLib/FdtPL011SerialPortLib.inf"). Addressing this issue in a SerialPortLib instance that underlies BaseDebugLibSerialPort seems wrong; either the DebugLib instance should cope directly with being called un-constructed (see again commit 91a5b1365075), or the DXE Core should log relevant information *at least* after library instances have been constructed. This patch implements the latter (only for the "BaseAddress" and "Length" values calculated by CoreInitializeMemoryServices()).

| | | | | | | | | | | | | | | | | | | | The MM communicate 2 protocol was introduced to factor out the mismatch between traditional MM, which requires the physical address of the MM buffer to be passed, and standalone MM, which copies the MM communicate buffer data into a separate buffer, requiring the virtual address. For this reason, MM communicate 2 carries both addresses, allowing the implementation to decide which address it needs. This hides this implementation detail from the callers of the protocol, which simply passes both addresses without having to reason about what the implementation of the protocol actually needs. Note that the old version of the protocol is retained, in order to support existing implementations that don't require this flexibility.

* MdeModulePkg/DxeCore: defer PE/COFF emulator registration to StartImageArd Biesheuvel2020-03-041-11/+13
| | | | | | | | | | | | | | | | | | | | | | | | EDK2's implementation of the LoadImage() boot service permits non-native binaries to be loaded (i.e., X64 images on IA32 firmware), but any attempts to start such an image using StartImage() will return EFI_UNSUPPORTED. The integration of the PE/COFF emulator protocol into the DXE core deviates slightly from this paradigm, given that its IsImageSupported hook as well as its RegisterImage hook are invoked from LoadImage, and by the time StartImage is called, no opportunity is given to the provider of the PE/COFF emulator protocol to prevent an image from being started if it only supports loading it. To address this disparity, let's move the invocation of RegisterImage() to the implementation of the StartImage() boot service, allowing the emulator to permit LoadImage() but reject StartImage() on images that turn out not to meet the requirements of the emulator as it is being started.

| | | | | | | | | | | | | | | | | | | | | When a boot loader examines the memory map, it can see that location 0 is available memory.

Leaving page 0 available is for legacy support purpose. Since we have deprecated the support of legacy, the solution is just reserving it so that it cannot be allocated for other uses.

* MdeModulePkg DxeCore: Fix for missing Memory Attributes Table (MAT) updateMike Turner2019-08-201-6/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Fpdt driver (FirmwarePerformanceDxe) saves a memory address across reboots, and then does an AllocatePage for that memory address. If, on this boot, that memory comes from a Runtime memory bucket, the MAT table is not updated. This causes Windows to boot into Recovery. This patch blocks the memory manager from changing the page from a special bucket to a different memory type. Once the buckets are allocated, we freeze the memory ranges for the OS, and fragmenting the special buckets will cause errors resuming from hibernate (S4). The references to S4 here are the use case that fails. This failure is root caused to an inconsistent behavior of the core memory services themselves when type AllocateAddress is used. The main issue is apparently with the UEFI memory map -- the UEFI memory map reflects the pre-allocated bins, but the actual allocations at fixed addresses may go out of sync with that. Everything else, such as: - EFI_MEMORY_ATTRIBUTES_TABLE (page protections) being out of sync, - S4 failing are just symptoms / consequences. This patch is cherry pick from Project Mu: https://github.com/microsoft/mu_basecore/commit/a9be767d9be96af94016ebd391ea6f340920735a With the minor change, 1.
